Very strange! Which version (platform) are you using? I've just tested the Linux version with and without my personal R'n'D directory (~/.rocksndiamonds), and everything looks like it expected.

Could you please check if the problem persists if you temporarily rename your personal R'n'D directory?

(BTW: But I've noticed that the CE graphics are all black (because the corresponding file "RocksCE.png" is all black), which looks like a bug in the packaging/build system. Version 4.0.0.1 is coming soon, I suspect... :-/ )

Update: Did the same test with the Windows version (tested on Windows 7), with the same result as above.

This value cannot be set anymore in recent R'n'D versions, and is set to "on" by default for all new R'n'D installations. So this problem should only occur if it was set to "off" with the last R'n'D version that allowed to modify it in the setup menu, or by manually modifying it in the setup config file.

Therefore, removing the personal R'n'D folder should force this value to be set to "on".
